Losing my mind need help

[hopbop]

Well, I have been running a 4 monitor set up for a few years, 3 monitors and a tv display above and for a long time this was fine I had them all running on there own cable to the GPU (current GPU is EVGA GeForce GTX 1080 FTW ). but I recently got an HTC Vive and quickly found I needed more ports so I did a little looking and upgraded my monitors to 3 Viewsonic VP2468's which have DP in and DP out for daisy chaining I thought this would be the way to go so it will only use one DP port for the GPU. cut to 3 hours now and my computer will only see one monitor and just repeat the display on the other two monitors I have tried everything I could google with no luck I'm pulling my hair out. If anyone can help I would be super grateful would even send you out my old monitors if you want them. there's still good 1080p ISP 60Hz.

 

Hardware

- GPU is EVGA GeForce GTX 1080 FTW

- Intel i7-6700k

- 32GB Ram

-Windows 10 64bit

 

Things I have already tried

• Updating drivers both GPU and Monitors
• Updating monitors Firmware
• turned off monitors auto-detect input (Viewsonic's guide recommended this) 
• Turned on MST
• unplugged all other displays form GPU (tv & Vive)

you're going to need to plug each monitor into it's own output otherwise yes using the same output will result in the machine sending only 1 signal to several monitors

Then why did they advertise the daisy chain ability and add the DP in and DP out ports on the monitors?

it would be useful in the event that you needed an output for a single image like a vive plugged into a computer with a single monitor , otherwise in your specific case it wouldn't be too useful.

you'd basically have to plug all your monitors into the gpu , then plug the vive into whatever monitor has the image on it that you want on the vive

@emosun, DisplayPort past revision 1.2 can daisy chain and support multiple monitors with different pictures.

 

So, @hopbop, you are correct about that:

What have you done in terms of multimonitor setup and management, for example, via nVidia's desktop manager/driver setup?  Also, just to make sure, you're not connecting the HTC Vive in that chain, correct?

Not much as my computer and N.D.M both only see one monitor.

I'm going to ask a basic question, please don't be offended...

 

Are you certain the initial cable going from the GPU to the first monitor is DisplayPort and not HDMI?

 

Further, I revised my original comment.  Make sure you aren't connecting the Vive in that chain.

Don't worry about Piney I won't be offended by basic questions. I know how helping people over the net with tech is a slow prosses with a long list of checks.

but yes it is Display port the first one on the GPU and should be running DP v1.4

Ok, and you say you enabled MST. Can you reverify that, and make sure it's set on all the monitors? Then, disconnect all but the first monitor, reboot.  Once back in Windows, add a single extra monitor to the chain and see if it behaves differently.  Windows 10 should see this automatically if the drivers are correctly installed and MST is turned on with any GPU using DisplayPort 1.2 or higher.

okay checked all monitors had MST on, unplugged all but first monitor, Rebooted, plugged in second monitor and computer did not see it.

[PineyCreek]

Mmm...is DisplayPort 1.2 mode set to on in the OSD of your monitor (or is that what you meant when you said you turned on MST)?

 

Also, depending on the monitor, you might need to turn that off on the last monitor in the chain.

DP 1.2 is on as well as MST

 

[PineyCreek]

Further odd suggestion...check and see if your Windows power plan is set to something other than High Performance.  If it is, change it and see if that addresses it.  Might be a power savings measure on the GPU.

 

Also, how long are the cables involved here?

power settings on Hight-P, cable lengths are 10ft form computer to first display and 3ft for second and 3rd

[PineyCreek]

There shouldn't be any barrier in your situation to using the displayport chaining then.  The monitors' settings are right, your cable lengths aren't long beyond the standards, PCI-E power is not in a savings mode, drivers are updated, GPU is capable of it.  Almost wish you had a Linux USB boot drive available to test using their kernel as well.

 

I kind of want to suggest uninstalling your display drivers using something like DDU before reinstalling.

 

What's your Device Manager show under Monitors (Right-click start Icon -> Device Manager, expand Monitors) and what do your Display settings show (Right-click start icon -> System, Display should be on top (build 1803)).

Device Manager shows one ViewSonic VP 2468 Series monitor, and I am on build 1803

I know everything is set correctly that's why I'm losing my mind lol

Well, I'm ashamed to admit that I'm running out of ideas.  Remaining:

 

1) Trying the uninstallation of the drivers via DDU, rebooting and reinstalling.

2) Disconnect main cable from GPU, wait a few seconds, reconnect.

3) Turn off DisplayPort 1.2 on last monitor in chain

4) Test on other OS like Ubuntu via LiveCD/USB

5) Power-cycle primary monitor with system up and running (probably pull power cable)

6) Contact eVGA

7) Contact ViewSonic

8) Cable swap on the off chance you got crap cables

9) Somehow appease the machine spirit you've somehow offended

well, Piney thanks for trying man ill go over the things in the list I have not tried yet.

question DDU is ...

Display Driver Uninstaller.  Super thorough cleanup utility for display drivers.

You might also get some new information if you wait a bit.  There's a whole other half of the planet that's not awake right now (although it's 1 in the morning where I'm at).

[PineyCreek]

Oh yeah, although your setup should work, if you're willing to spend a bit of money you could try a DisplayPort hub to see if you get different results.  Won't be as clean as you like, but you could try.  You could always return it if you still had the problem.

ya, its 2 am for me. I think sleep might help me at this point been slamming head to a wall now for 5 hours.

 

thanks again for the help man. its a bit reassuring knowing I'm not crazy and my system is a bit wack

display hub might be the way to go all I'm trying to do is not use every port on my GPU. and I can hide the hub behind the monitor bar and still look clean. might just go that rout tomorrow. that should be an easy fix.
